bp-album with bp on 2ndary blog

as i have a heavily modified wp theme running on the main blog i decided to, as suggested, install buddypress to a 2ndary blog called “community”.

working perfectly, except one issue with bp-album … i asked on the author’s website, as i didn’t get an answer i thought maybe here some pro could have a suggestion for my problem

basically the pictures in /members/xxx/album are showing a 404.

i traced it down to the fact that i got buddypress installed on a 2ndary blog. the album is searching for the image on â€œhttp://xxx.com/community/wp-content/â€¦â€ in my case (whereas /community/ is the root dir of buddy press but not the root dir of wordpress as i explained before).

how can i set the picture path to root â€“ or strip out â€œcommunityâ€ via modrewrite?
